We've pulled the 40-litre fuel cell out of the boot and re-instated the OEM tank. We will pull from both sides into a surge tank with twin pumps (one is a secondary in case I have a primary failure) and gravity feed these tanks from a 45 litre aux tank above the OEM tank via -24 hoses (all sealed under a bulkhead). We'll fill the aux tank. I'll put senders in the OEM tanks and have the Motec monitor fuel burn so I know have much fuel I have left.

Engine bay returns to the surge pot and overflows back into the aux tank. This means all pumps will run submerged unless I run the EOM tanks low.

All the fuel weight is inside the wheelbase (surge tank excepted).

The surge tank will go in the boot - again it is all sealed off from the cockpit.

Will use a common billet surge tank - see here:

We have to upgrade the cage - it was OK for club-level track-days but it needs additional bar-work to qualify as a national level cage. PITA as the screen needs to come out for the fabricator to get access to weld the new bars ....

Only waiting for steering hub adaptor and bolt-on removable steering wheel hub. May need a new steering wheel - current one is deep dish and all the extra stuff probably means a flat wheel.

My job for the break is to program the dash with everything we need (general layout for page 1, then page 2 and page 3 plus set up predictive lap times for our main circuits). Busy .. busy

BTW - found a dyno sheet for the engine ........ ~350hp atw - seems healthy .... will scan and post sometime
